A 22-year-old hit 98mph on country lanes before ploughing into a stationary car and running off, leaving his dying victim trapped in the wreckage.
Myles Woollett, of Mereworth, has now been jailed for six years after causing 23-year-old Claudia-Rose Moor's death on the A21 at Mountfield.
Emergency services were called at 6pm on April 25, following the crash involving the Vauxhall Adam driven by Woollett.
He was seen driving recklessly at high speeds before attempting to overtake a vehicle.
He lost control and collided with Claudia-Rose's car.
Claudia-Rose, who was a team leader at the Co-operative and lived in St Leonards, suffered life-threatening injuries in the crash, and sadly died two days later at the Royal Sussex County Hospital in Brighton .
On Monday, at Lewes Crown Court Woollett admitted causing death by dangerous driving and causing serious injuries by dangerous driving to a passenger in his own vehicle.
He was also disqualified from driving for seven years and was told he would need to take an extended retest before he would be allowed to obtain his licence.
It was revealed in court that Woollett, from Butchers Lane, had wanted to meet his cousin on the day and go for a drive.
Less than an hour before the crash staff at a Waitrose store in Paddock Wood had refused him entry because they believed he had taken alcohol or drugs.
Video footage taken from his cousin’s phone from inside the car and shown below showed Woollett’s dangerous driving.
Witnesses saw him attempting dangerous manoeuvres as he approached the A21 at Mountfield near Robertsbridge, including near misses with other vehicles.
Moments before the crash, he reached speeds of up to 98mph.
Woollett then attempted to overtake a car but lost control as he tried to avoid a head-on collision with another oncoming vehicle.
This caused him to veer across the road, colliding with Claudia-Rose’s Ford Ka which was stationary in a layby.
Woollett then left the scene by climbing over a fence and running across fields, leaving Claudia-Rose and his passenger trapped with serious injuries.
He was arrested the next day at the address of a relative 20 miles away in Yalding.
After the sentencing Claudia-Rose's family says they have been "robbed of their gorgeous girl".
Her mother Nicola Moor, 47, said: “Claudia’s charismatic personality made her such a great friend to everyone, she was incredibly funny and always brought laughter and noise, she never saw wrong in others and was always the first to offer aid to others less fortunate than herself.
“Claudia was full of compassion and generosity, her heart brimming full of love for her family and her so many friends.
“As Claudia’s mother, I am so incredibly proud of her morals and what she stood for, so full of kindness and support of others, she was incredibly beautiful both inside and out, a strong and fiercely independent young woman who would give her love to others so freely.
“It has been the greatest honour to be mummy to Claudia, I will continue to miss my brilliant best friend every moment of every day for ever more.”
DI Sue Neilson from the Serious Collision Investigation Unit said: “This case demonstrates the devastating consequences of a young motorist driving at speed.
“The combination of excess speed and inconsiderate driving are two of the main factors for why people are killed and seriously injured on our roads.
“We welcome the sentence passed by the judge as a warning to other motorists, and to take a dangerous driver off our roads.”
